Beit known that'I, SI'MEON' MILLS, of Madison, in the county of Donc, ond Stets of Wisconsin, have invented invented certain new and useful Improvements in Machines for Grinding Pest and similar substances.; and I do hereby declare that the following is a full, clear, und Aerect description'thcreof, reference 'being had to the accompanying drawings, mcking'pert of this specification, and to the letters of reference marked thereon, like yletters indicating like pnrts'wherever. they' occur.

Asubstancesu In the drowings- To enable others skilled in' the art to construct' ond use'my invention, I will procedtoldes'crihe it. My invention consists of anew and improved machine' for grindingond compressingpet and-,similar Figure 1 is a. vertical sectional view on the line z n: of 'igl 2. Figure 2 is a. side elevation, and

i Figure 3 is a view of a portion of the moehinedetoched. Y

In constructing my'machinerI'm'skc o. strong ease or box, A, consisting of two ports B' Q hinged together 'b and closely tting with a. deviccz'Drfor fastening them,n.s shownin lig. 2l Within the ceseAI mount two spirnlly tinted" conicsl rollers or screws-E, parallel with each other, and with th'eir hearings in either'end of the cese, in nsuch ow'y thot they .will mesh into one another, ssvshownvin g. 7. O'ver the feed -end of' the rollers I plecee feed-hopper, G, ss shown' in iig. 2,'endwitl1in sndneor the lower side Vof the hopper-'two grooved feed-l rollers a b to drow the feed through this hop/per G und on to the spiflly'uted rollers ors'crows E.` The form 'of Vthe `spirslly iluted rollers or screws is 'shown ,clearly in lig'. 8. At the delivery end of 'the vspirslly tlutecl rollers' or screws E I extend Vthe upper eide B of 'thencose A, so es to makie'square hollow tube, c, for the delivery of thesubstance p ztssing from therollers F. Within this hollow tube@ I insert o mnndrel, d, tapering in form, by attaching its smaller end t'o the cnseAand having its larger cd'loose ond extending nearly to thev mouth of the hollow tube c, osfshown by the dotted 'lines in iig..2.` The journal of one of the spirally iuted rollers I-er'rtend famenoughheyond Ythe cose A to receive the -pulley e ond-the' driving-wheel f, os shown in iig. 2.

I also extend the journals of 'the grooved feedrollers ab isr enough beyond the hopper Gto receive the pulleys h, as shown in'g. 2. I thn'pess a cord or holt around the Eulleys e'hh in such s. way ss vto canse the spirslly tinted rollers or screws E and the groved rollers al; tqfrev'hie toward eschother, ns shown by the arrows in* iig. I.'

In operstingmy machine, I tl'row the peut or' other substance into thohopper The revolving grooved fee-rollers o6 'force the pest/down` upon the spirolly grooved rollers E E. As these rollers EV E mosh into eooh other, the turhingo one of them causes the other to revolve, ondes' they revolve'the pest is droiivn between and ground, and ut the some time is forced ynlongtheirgrooves totheir d eliveiy'end, ond. there forced into tho hollow tube c ond through the tube 'e'. As the'm'ondrel d is in th'e centre Aof thc'tubo c, ond larger at its outer lthan :it its inner end, 'thc peat, in passing through,'is,delivered in the shape of o. square hollow tubo and'rmly pressed orfcr'uied by the largeenil of themzmdrcl. r Y A It is obvious thot the spirolly ilntcd rollers vmoy-'he,mode conical or stralight, es in either cose the pontoiother substance will. be forcecllol'ong from their feed to their delivery ends, on'dth'ut they muy he ploced in-eithcr o'horizontcl'or vertical position, und that thr` mnchine maybe mode of metal or wood, or of'hoth conibinod;

-Having thu's described my invention;L what I'clsim, irsl 1. Therspirally {luted cylinders'or Vrollers E, whether conical or straight, so constructed und arranged that both are propelled `in o rototory manner by the opplication of power to one without gearing, sobstsntisillyas` described and for the purposes s ct forth.

2. The ,grooved feed-rollers a b, in combination with the Ailuted rollers E, when lcons'm'uctedjund' arranged to operate os described sind for the purposes set forth.

S. Thejspirolly il'utcd. rollers E, in combinationjvith cach other and with thc groovcd feed-rollers a` blond l mandrel d, 'when arranged to opcro'tc in a close-fitting eusers'ubstontinlly :is described and for the purposes set' forth. 'Y
